I was just wondering if anyone has heard of or used any RainX substitutes. Not that I don't like RainX, it works well, but I feel I have to reapply it often. Now I have stopped at our local Ziebart and they have the Aquapel gas treatment for windows for $24.99USD and it has a 6mo warranty. Anyone have this done and care to comment or have any comments on this procedure, thanks.
